I waited for a long time to get one (WMR) because of the trigger reviews. Finally I got it this winter. I simply love that gun. Very innovative piece of engineering and scary accurate for an out of the box semi. My trigger came at about 4.5 lbs with noticeable creep. I polished it to bring it down to 3.8lb after about 500 rounds through it. It is not a target trigger by any means but much better than what I expected after reading about it (and significantly better than a 10-22 factory trigger). My 512 WMR averages about 1/2 in at 50 m with cheap 40 gr cci ammo, 3-9x40 Nikon, shooting of Caldwell bags. Last weekend I used a Harris bi-pod, shooting prone and it did 1in groupings at 75m consistently (light winds). I have never had FTE or FTF but I keep it clean. The barrel appears to be the same as on the 455 series but it seems to be pinned to the receiver in addition to the 2 screws that are used on 455s. If you are purchasing from a dealer, ask if they can measure the trigger for you prior to the purchase.
